14.6 would be high normal, 13.5v would be acceptable battery charging voltage. Check voltage across the battery terminals, leave the black ground wire at the battery post (-) move the red volt lead to the large wire post at the alternator if the voltage is different you have a voltage drop (youtube voltage drop there is a good video there). At rest engine off battery voltage should be 12.6 volts at rest if battery is charged and good.
